Serpentine spring

The serpentine spring is an important part of the JS serpentine spring coupling, and it is also a basic accessory that determines the quality of the coupling. It is applied to various serpentine spring couplings, which can protect the main body of the coupling and improve the coupling. Life.

Most serpentine springs suffer from fatigue failure, and their life depends on the fatigue strength of the spring. The force of the spring is mainly alternating bending stress, torsion stress, tension and compression stress, etc. Under the action of alternating stress, fatigue cracks begin at the defect and continue Fracture, so in the process of processing to harden the surface to produce compressive stress.

Springs made of hot-pressed spring steel often have decarburization and oxidation defects on the surface. Heat treatment of many springs will also cause such problems on the surface, which will cause fatigue damage.

After the serpentine spring is tempered at medium temperature, the compressive stress generated by carbonitriding and the compressive stress of quenching are mostly eliminated. At this time, shot peening can improve the surface hardness, eliminate surface defects, and offset the tensile stress generated during the operation of the spring. Thereby further increasing fatigue.
